IMPROVEMENT IN UNHAlRlNG-MACHINES.

Specification forming part of Letters Patent N 0. 221,545, datedNovember 11, 1879; application filed. August 30, 1879.

To all whom it may concern:

Be it known that 1, WILLIAM GERBER, of Fremont Centre, in the county ofNewaygo and State of Michigan, have invented an Improvement inUnhairing-Machines, of which the following is a specification..

The nature of this invention relates to certain new and usefulimprovements in theconstruction of devices for removing hair from hides.preparatory to their being tanned; and the invention consists in asuitable frame which supports a turn-table and track, by means of whichthe hides may be brought under the fleshing-knives, which are secured toan endless belt or chain, arranged and operated as more fullyhereinafter set forth.

Referring to the drawings, Figure 1 is a perspective view. Fig. 2 is asectional plan, showing the arrangement of levers which operate theturn-table and truck. Fig. 3 is a vertical longitudinal section on linea: m, Fig. 1. Fig. 4 is aperspective view of turntable truck.

In the accompanying drawings, which form a part of this specification, Arepresents a suitable frame, within which at each end are properly hungthe frames B, which are provided .with the inwardly-projecting V'shapedlevers 0, their inner ends being connected together by a cord or chain,a, which passes through the treadle-lever D, the inner end of which ispivoted to the frame, as shown at b. On the two outer corners of theframes B are secured upwardly-projecting studs 0, upon which rests thetrack-frame E, the weight of which depresses thefr-ames B and elevatesthe inner the frame H is journaled ashaft, lglwhich may be driven in anyconvenient manner, and which carries the pulleys d. The forward ends ofthe frame I are recessed to receive the blocks L, in which is journaleda shaft, M, which carries pulleys 6. Around these pulleys e and cl passendless belts or chains N which carry the fleshing-knives 0. Should thebelts N become loose after using for a time, they can readily betightened by driving the Wedges h down back of the blocks L, which willforce them outwardly, and thus stretch or tighten the belt, as may bedesired.

In operation, a hide with the hair side uppermost is laid upon ,theturn-table, when the operator rolls the table under the frame whichcarries the knives. He then depresses the lever D with his foot, andthus, by means of the devices hereinbefore described, elevates thetable, bringing the hide in contact with the fleshing-knives, whicheffectually remove the hair.

By the use of this machine much time and labor are saved, and the workis more effectually done than when performed by hand in the usual way.

What I claim as my invention is 1. In a machine for unhairing hides, thecombination, with a turn-table having a revolving and sliding motion,and supported on levers which give it avertical movement, of a frameprojecting over such turn-table, and having fleshing-knives carried byendless belts, substantially as described and shown.

2. In a machine for unhairing hides, the combination, with theturn-table G, truck F, and track-frame E, of the frames B and levers OD, substantially as described and shown.

WILLIAM GERBER.
